If you have noticed that the girls repeatedly rub their arms and legs, it is because they are being constantly bitten by mosquitoes, which are attracted by the numerous ponds and water features in the gardens (and probably by the number of visitors available to bite). Much as they appreciated the beauty of the water features, the girls tried to avoid the biting insects by moving to a more open area of the park. Ewa needed to pee and so sat on one of the stone benches, opened her legs wide, pulled her panties aside and took a long pee on to the ground.
